Instructions  
Your new coffee grinder is easy to operate and maintain. Before you place it in service, please have all personnel  
familiarize themselves with these instructions; then keep this manual in a convenient place for ready reference.  
Set-up Procedures  
1. You, the user, must determine the quantity of coffee you want to dispense as various types of coffee and  
brewing equipment require different quantities to obtain a quality cup of fresh ground, fresh brewed coffee.  
Note: Because of the inherent properties of some decaffeinated coffee, it may be necessary to dispense a slightly greater  
amount to achieve the desired level of flavor extraction as in regular coffee. This should be evaluated based on the coffee  
you use as well as the brewing equipment used.  
2. Adjust the timer inside the grinder if necessary, to dispense the desired weight of ground coffee (see Timer Adjustment  
Section on page 3). All grinders are factory set to deliver approximately 2 ounces of ground coffee. This weight is  
approximate, as the density of all coffee beans is not the same. The only way to ensure the desired portion is being  
dispensed is to weigh the coffee after it has been ground.  
3. The grind texture can be adjusted, if necessary, to a finer or coarser grind (see “Grind Adjustment” section on page 5).  
The grind is factory set to deliver a standard autodrip grind.  
How to Operate  
1. Fill the hopper with the appropriate amount of whole bean coffee.  
250RH Models: Place full hoppers on machine making sure the base of each hopper is seated in designated area.  
(Refer to Figure A)  
2. Place the brew basket with coffee filter on rails (or basket arms).  
3. Choose the type of coffee you wish to grind by pressing the rocker selection switch.  
4. Push the start button on the front of the grinder.  
5. When grinder stops, remove the brew basket.

Grind Selector™  
For Models 115AB and 250AB:  
Models equipped with a Grind Selector™ are designated with a “B” at the end of the model number (Model 115AB & 250AB). If  
your grinder is equipped with a Grind Selector™, refer to the following information:  
The Grind Selector™ allows you to set the grinder to coarse or fine on any of the 250AB four grind selections:  
regular small, regular large, decaf small, or decaf large.  
The following are some recommended use conditions:  
Coarser Settings  
Regular Settings  
Larger portions - 8 oz or more  
(urns)  
Decaffeinated coffee  
Smaller portions - 7 oz. or less  
(bottle brewers or airpots)

Coffee Grind Profile  
Before shipment, this grinder has been tested with coffee and has been accurately adjusted to deliver a  
standard autodrip grind.  
The Grinding Burrs are made of an extremely hard and wear resistant alloy. From time to time, grind  
adjustments (see instructions below) may be necessary as the burrs wear. If the grind runs coarser than  
expected after normal adjustment and the grind time has increased, the burrs may have excess wear and should be  
replaced. The burrs are warranted for 3 years or 30,000 pounds of coffee. See your warranty for details. New burrs should  
always be installed as a pair, never one or the other, as they are accurately ground and lapped in pairs. Old burrs cannot be  
resharpened.  
Grind Adjustment  
For Models 115A, 250, 250A, 250RH-2, 250RH-3  
Tools Required: Phillips and Large Blade Screwdrivers, Pliers  
In order to adjust the grind follow these steps: (see Figure D)  
Adjusting Screw  
Lock Nut  
(86340)  
Adjusting Screw  
(86341)  
1. Remove Upper Front Plate by removing the four screws in the corners.  
2. Loosen Adjusting Screw Lock Nut by turning counter clockwise.  
3. Turn slotted Adjusting Screw clockwise to make grind finer or  
counter-clockwise to make grind coarser. Generally a 1/8 to 1/4 turn  
will provide the desired adjustment.  
Note: Use dial on grinder cap as reference. Do not turn more than  
one notch before testing new Grind Adjustment.  
Grinder Cap  
(87131)  
4. After adjustment has been made, tighten Adjusting Screw Lock Nut.  
Figure D: Grind Adjustment  
5. To visually inspect grind adjustment, test grind a small portion of coffee  
and re-adjust if necessary.  
Note: Adjusting the grind may alter the portion of coffee dispensed. After grind adjustment,  
weigh portion and adjust, if necessary (see “How to Adjust the Portion”).  
Current  
It is absolutely essential that full voltage and amperage always be available as it takes full power to grind  
coffee. NEVER connect to an overloaded line or a two or three way plug, otherwise serious damage to the motor may result.  
Do not use an extension cord.  
Protection  
This grinder is equipped with both a circuit breaker and a shear disc to protect motor and burrs if a foreign object, such as a  
nail or rock, gets into the coffee.  
Circuit Breaker  
This grinder is equipped with a circuit breaker to protect the motor from overloading. When the circuit breaker operates, the  
reset button will pop out approximately 1/4” which cuts off the power to the grinder. The reset button is located above the  
power cord on the back of the grinder. To reset the circuit breaker, push the reset button in. You will hear a click as it resets.  
If the grinder does not operate after resetting the circuit breaker, there may be an obstruction in the grinding mechanism that  
is stalling the motor. In this case, the Grinder Head should be cleaned out as described in the Shear Disc Replacement  
section of this manual.  
Lubrication  
All bearings have been oiled for life. No further oiling is necessary.

Cleaning Instructions  
The outside of the machine can be cleaned with a damp cloth or common household polishing wax. Grinding parts should  
be cleaned with a stiff brush or dry cloth. Do Not Use Water. See “Shear Disc Replacement” for instructions on assembling  
and disassembling of grinder parts. Before reassembling, wipe motor shaft with 2 or 3 drops of common household lubricat-  
ing oil in the area of feedworm engagement to make assembly easier.  
For Models 250RH-2, 250RH-3:  
Regular usage of the coffee hoppers will cause oils to accumulate on the inner surface, requiring occasional cleaning.  
1. Remove hopper from grinder and empty all beans.  
2. Use a soft, damp cloth with a small amount of liquid soap and clean hopper. Use a clean, damp cloth to remove the  
soap residue. Do not immerse or fill hopper with water.  
3. Allow hopper to completely air dry before refilling with beans.  
4. Once the hopper is dry, refill with whole bean coffee, cover and replace on grinder.
